Comparative study on the technical efficiency of potato production between China and Russia

Research on the technical efficiency of crop production between China and Russia is of great significance for comparing the advantages of agricultural production efficiency and promoting the agricultural production cooperation between the two countries. Based on the Three stage DEA method, this paper selected the potato production data of 31 Provinces in China and 79 states in Russia in 2017 and evaluated the technical efficiency of potato production in China and Russia under the influence of land quality factors. The results of the one stage DEA test showed that the technical efficiency, pure technical efficiency, and scale efficiency of Russian potato crops were higher than those of China. This indicated that the production technology and management level of Russian potato crops were higher, and the scale of returns of Chinese and Russian potato production was increasing. After eliminating the influence of land quality factors in different regions, the situation had changed greatly. The technical efficiency and scale efficiency of potato crops in China were significantly higher, indicating that the production technology of potato crops in China was significantly higher, while the pure technical efficiency was slightly higher in Russia. At the same time, the increasing trend of returns to scale of potato production in the two countries was more obvious. The conclusion of the study had a certain reference value for analyzing the level of agricultural production technology and production management in China and Russia and strengthening agricultural cooperation.
